I need to know the torque specs for the belt tensioner pulley on

idler pulley has a torque spec of 37ftlbs the tensioner has a internal pre load so when you use the 19mm hex plug to move it it sets itself when you release it

Serpentine belts use a spring-loaded tensioner pulley to keep them tight. If the belt is not tight, either it is not routed properly or the tensioner spring is broken. Look for a pulley mounted on an arm by itself, that turns no device such as an air conditioner or pump.

there is no spring tensioner on some of the 3.0 engines. See instructions below. I will paste a pic on the version that DOES have a tensioner at the bottom of this post.

3.0L Engine-Except SHO
ALTERNATOR BELT WITHOUT AUTOMATIC TENSIONER

1. Loosen the adjusting arm and pivot bolts.
2. Turn the alternator belt adjusting screw counterclockwise until the old belt can be removed.
3. Remove the belt.

To install:

1. Install the new belt over the pulleys. Check that all the V-grooves make proper contact with the pulleys.
2. Adjust the belt tension, then tighten the adjusting arm and pivot bolts.

3.0L SHO Engine
ALTERNATOR BELT
See Figure 2

1. Loosen the nut in the center of the idler pulley.
2. Loosen the idler adjusting screw until the old belt can be removed, then remove the belt.

To install:

1. Install the new belt over the pulleys in proper contact with the pulleys.
2. Adjust the new belt to specifications as follows: Turn the idler pulley nut to the right to tighten the belt to a specification of 220-265 lbs. (980-1180 N). Torque the idler pulley nut to 25-37 ft. lbs. (34-50 Nm).

POWER STEERING AND AIR CONDITIONING BELT
See Figure 2

1. Remove the alternator belt.
2. Loosen the nut on the tensioner pulley.
3. Turn the belt adjusting screw on the tensioner counterclockwise until the belt can be removed, then remove the belt.

To install:

1. Position the new belt over the proper pulleys, making sure the V-grooves are properly seated.
2. Install the alternator belt.
3. Adjust the power steering and air conditioning belt to a specification of 154-198 lbs. (690-980 N) with a belt tension gauge.
4. Adjust the alternator belt.

3.0L Engine (Except SHO) and 3.8L Engine
VEHICLES THROUGH 1993 WITH AUTOMATIC TENSIONER
See Figures 4 and 5

1. Insert a 1 / 2 in. breaker bar into the square hole in the tensioner.

On the 3.8L engine, the tensioner has a1/2in. square hole cast into the rear of the tension arm directly behind the pulley. On the 3.0L engine, the1/2in. square hole is cast into the spring housing on the front of the tensioner.

1. Rotate the tensioner clockwise and remove the belt.

Fig. Fig. 5: 3.8L belt schematic-1993 shown

To install:

1. Install the drive belt over all the pulleys, except for the alternator pulley on the 3.0L engine for vehicles through 1992, or the idler pulley for 1993 3.0L vehicles.
2. Rotate tensioner counterclockwise and install the belt over the alternator pulley. Make sure that all the V-grooves make proper contact with the pulleys.
3. On the 3.0L engine, install the alternator belt for vehicles through 1992.
4. For 1993 3.0L vehicles, install the drive belt over the idler pulley.

OK, one doesn't need a belt routing diagram to reinstall a new belt.

Just route the belt so that one by one you put the ribbed part of the belt up against the ribbed pulleys, and the smooth part of hte belt up against the smooth pulleys. Do this until one arrives at the tensioner and release tension with a breaker bar to put the belt on the final tensioner pulley.

Check that the tensioner has enough spring load for the belt to maintain the right friction against all of the serpentine pulleys.

That's all there is to it.

Not sure if you have the 3.0L 2V or the 3L 4V so heres both. Hope it helps.. Cobra,, :-)

Once you align the top and bottom timing marks, and install the belt and tight the belt tensioner, you are done, there is no distributor to adjust ignition timing, it is computer controlled. The torque for the crankshaft bolt is 80 foot pounds. Hope this helps, let me know.

My sincere apologies for the delayed response.
I am personally going back to answer your unanswered questions.
I have only been a free contributor to this site for the past 4-months.

I do not know if you still need this information, but I am going ahead and answering it anyway.

CLICK on the following LINK. It has several Belt Diagrams, one which will match your specific engine and options (AC/No AC, Power Steering, .etc) that you will need.

Regarding HOW:
Standard Rules to Removal the Serpentine Belt:
1. Find the Tensioner(s). (See the Diagrams on Link)
2. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
Standard Rules for Installing the Serpentine Belt:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left, right etc.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum ("open") allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. While keeping the Tensioner Pulley/Arm "open" Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them.
Let me know if this helped...
Again my apologies..

Starting at the crankshaft pulley, and going clockwise, the belt leaves the crank pulley,
Goes around the tensioner,
Goes around the water pump
Goes around the alternator
Goes around the upper idler
Goes around the Power Steering pump
Goes around the air conditioner pulley
then goes back to the Crank pulley
